"An Eco-Morphodynamic Modelling Approach to Estuarine Hydrodynamics & W" by Kristian Kumbier, Kerrylee Rogers et al.

Tidal inundation is the primary driver of intertidal wetland functioning and will be affected by sea- level rise (SLR). The morphology of estuaries and friction across intertidal surfaces influences tidal propagation; accordingly, sea-level rise not only increases inundation frequency, but will also alter other tidal parameters, such as tidal range. To investigate responses of estuarine intertidal vegetation, primarily mangrove and saltmarsh, to SLR an eco-morphodynamic modelling approach was developed that accounted for some of the feedbacks between tidal inundation and changes to wetland substrate elevations. This model partially accounts for adjustment in estuarine hydrodynamics, and was used to examine the potential effect of SLR on mangrove and saltmarsh distribution in a micro-tidal channelised infilled barrier estuary in southeast Australia. The modelling approach combines a depth-averaged hydrodynamic model (Telemac2D) and an empirical wetland elevation model (WEM) that were co ....

Frontiers | Sensitivity Analysis of Flash Flood Hazard on Sediment Load Characteristics

Ongoing changing climate has raised the attention towards weather driven natural hazards, such as rain-induced flash floods. Flooding model provides an efficient tool in flash flood warning and hazard management. More and more evidence showed significant impacts from sediment on hydrodynamic and flooding hazard of flash flood. But little information is provided regarding flooding hazard sensitivity to sediment characteristics, which hampers the inclusion of sediment characteristics into flash flood warning system and hazard management. This study used 1D model to simulate flood hazards. After calibrating and validating the hydrodynamic model, we carried out simulations to test the sensitivity of flood hazard to sediment characteristics of inflow point, size distribution and concentration. Our results showed that sediment from highly erosive slopes affects the flooding hazard more than sedimentsfrom watershed. This is particularly true when sediments are fine particles with medium size ....

Flood Hazard Areas Description & Limitation: The map (from the link below) displays the locations of
potential flood vulnerable areas & flood vulnerable WASH infrastructures. The aim of this map is to help
planners & decision makers to identify priority area for interventions at Uknia & Teknaf Upazila camps. It is
not designed as a stand-alone tool for detailed site planning decisions. The map does not provide any information
about the water flow & flood hazard indicatives areas are not ground proofed. They should be ground verified
& combined with specific on-site evaluations and expertise. The flood zones do not necessarily imply exposure ....
